1. In a' hurdle of the class described, a pair oi standards, a cross-barsecured to and connecting the upper ends of said standards, extensionsfor said standards pivoted thereto, the pivot means including slots inthe extensions andpins in the standards engaging the slots, said slotsextending longitudinally, 'a cross-bar kconnecting said standardextensions, said extensions having notches in their side edges forreceiving portions of the cross bar of the standards, said notches beingof greater length than the width of the cross bar and keeper platesconnected with the' extensions and extending over portions of the l lnotches for holding the said cross bar in said notches, when theextensions are in raised position with the pivot pins engaging the upperend of the slots.

2. A convertible high and low hurdle comprising a pairv of base members,a spreader bar `secured to and extending between said base memextensionsat said one edge thereof and overlying one endvof said notches forengaging the firstnamed cross-bar when said standard extensions aredisposed in an extended position with respect to said standards.

3. A convertible high and low hurdle comprising a pair of base members,a spreader bar secured to and extending between said members, standardsrising from said base members, a cross-bar connecting the upper ends ofsaid standards, standard extensions pivotally and slidably connected atone end thereof with said standards, a cross-bar connecting the freeends of said standard extensions, said standard extensions beingprovided in one edge thereof with notches to accommodate the first-namedcrossbar and keeper plates secured on said standard extensions at saidone edge thereof and overlying one end of said notches for engaging thefirsta lowered position with respect to said standards,

and the keeperplates on said standards serving to engage the cross-barconnected with the standard extensions for retaining said-cross-barwithin the notches of said standards.

4. In a hurdle of the class described, a lower pair of upright members,an upper pair of upright members, one pair having longitudinallyextending slots therein, pins Acarried by the other pair and passingthrough the slots for slidably connecting thetwo pairs together, across'bar connecting the members of onepair together and the members ofthe other pair having notches in edge portions thereof of greater lengththan the Width of the cross bar and keeper plates connected with thenotched edges and extending over portions of the notches for holding thecross bar in said notches, said plates permitting the cross bar
